Studies on antimicrobial activity, in vitro, of Physalis angulata L. (Solanaceae) fraction and physalin B bringing out the importance of assay determination

Complex physalin metabolites present in the capsules of the fruit of Physalis angulata L. have been isolated and submitted to a series of assays of antimicrobial activity against Pseudomonas aeruginosa ATCC 27853, Staphylococcus aureus ATCC 29213, S. aureus ATCC 25923, S. aureus ATCC 6538P, Neisseria gonorrhoeae ATCC 49226, Escherichia coli ATCC 8739; E. coli ATCC 25922, Candida albicans ATCC 10231 applying different methodologies such as: bioautography, dilution broth, dilution agar, and agar diffusion techniques. A mixture of physalins (pool) containing physalins B, D, F, G inhibit S. aureus ATCC 29213, S. aureus ATCC 25923, S. aureus ATCC 6538P, and N. gonorrhoeae ATCC 49226 at a concentration of 200 mg/µl, using agar dilution assays. The mixture was inactive against P. aeruginosa ATCC27853, E. coli ATCC 8739; E. coli ATCC 25922, C. albicans ATCC 10231 when applying bioautography assays. Physalin B (200 µg/ml) by the agar diffusion assay inhibited S. aureus ATCC 6538P by ± 85%; and may be considered responsible for the antimicrobial activity.

Attrition in the Swiss Household Panel: Is change associated with later drop-out?

This study examines the importance of change in characteristics and circumstances of households and household members for contact and cooperation patterns. The literature suggests that there might be an underrepresentation of change in panel studies, because respondents facing more changes would be more likely to drop out. We approach this problem by analysing whether previous changes are predictive of later attrition or temporary drop-out, using eleven waves of the Swiss Household Panel (1999-2009). Our analyses support previous findings to some extent. Changes in household composition, employment status and social involvement as well as moving are associated mainly with attrition and less with temporary drop-out. These changes affect obtaining cooperation rather than obtaining contact, and tend to increase attrition.

Artificial muscle to wash blood out of fibrillating atrium: an alternative to lifelong anticoagulation.

The Atripump is a motorless, volume displacement pump based on artificial muscle technology that could reproduce the pump function of normal atrium. It could help prevent blood clots due to blood stagnation and eventually avoid anticoagulation therapy in atrial fibrillation (AF). An animal study has been designed to assess mechanical effects of this pump on fibrillating atrium. The Atripump is a dome shaped silicone coated nitinol actuator. A pacemaker like control unit drives the actuator. In five adult sheep, the right atrium (RA) was exposed and dome sutured onto the epicardium. Atrial fibrillation was induced using rapid epicardial pacing (600 beats/min). Ejection fraction of the RA was obtained with intracardiac ultrasound in baseline, AF and Atripump assisted AF conditions. The dome's contraction rate was 60/min with power supply of 12V, 400 mA for 200 ms and ran for 2 hours in total. Mean temperature on the RA was 39+/-1.5 degrees C. Right atrium ejection fraction was 31% in baseline conditions, 5% and 20% in AF and assisted AF, respectively. In two animals a thrombus appeared in the right appendix and washed out once the pump was turned on. The Atripump washes blood out the RA acting as an anticoagulant device. Possible clinical implications in patients with chronic AF are prevention of embolism of cardiac origin and avoidance of hemorrhagic complication due to chronic anticoagulation.

Detection of human growth hormone doping in urine: out of competition tests are necessary.

The misuse of human growth hormone (hGH) in sport is deemed to be unethical and dangerous because of various adverse effects. Thus, it has been added to the International Olympic Committee list of banned substances. Until now, the very low concentration of hGH in the urine made its measurement difficult using classical methodology. Indeed, for routine diagnosis, only plasma measurements were available. However, unlike blood samples, urine is generally provided in abundant quantities and is, at present, the only body fluid allowed to be analysed in sport doping controls. A recently developed enzyme-linked immunosorbent assay (Norditest) makes it now possible, without any extraction, to measure urinary hGH (u-hGH) in a dynamic range of 2-50 ng hGH/l. In our protocol, untreated and treated non-athlete volunteers were followed. Some of them received therapeutical doses of recombinant hGH (Norditropin) for one week either intramuscularly (three increasing doses) or subcutaneously (12 i.u. every day). The u-hGH excretion after treatment showed dramatic increases of 50-100 times the basal values and returned to almost the mean normal level after 24 h. u-hGH was also measured in samples provided by the anti-doping controls at major and minor competitions. Depending on the type of efforts made during the competition, the hGH concentration in urine was dramatically increased. Insulin-like growth factor binding proteins and beta 2-microglobulins in urine and/or in blood could be necessary for the correct investigation of any hGH doping test procedure.

Insecticide treated mosquito nets for malaria control in India-experience from a tribal area on operational feasibility and uptake

The study assessed the operational feasibility and acceptability of insecticide-treated mosquito nets (ITNs) in one Primary Health Centre (PHC) in a falciparum malaria endemic district in the state of Orissa, India, where 74% of the people are tribes and DDT indoor residual spraying had been withdrawn and ITNs introduced by the National Vector Borne Disease Control Programme. To a population of 63,920, 24,442 ITNs were distributed free of charge through 101 treatment centers during July-August 2002. Interview of 1,130, 1,012 and 126 respondents showed that the net use rates were 80%, 74% and 55% in the cold, rainy and summer seasons, respectively. Since using ITNs, 74.5-76.6% of the respondents observed reduction of mosquito bites and 7.2-32.1% reduction of malaria incidence; 37% expressed willingness to buy ITNs if the cost was lower and they were affordable. Up to ten months post-treatment, almost 100% mortality of vector mosquitoes was recorded on unwashed and washed nets (once or twice). Health workers re-treated the nets at the treatment centers eight months after distribution on a cost-recovery basis. The coverage reported by the PHC was only 4.2%, mainly because of unwillingness of the people to pay for re-treatment and to go to the treatment centers from their villages. When the re-treatment was continued at the villages involving personnel from several departments, the coverage improved to about 90%.Interview of 126 respondents showed that among those who got their nets re-treated, 81.4% paid cash for the re-treatment and the remainder were reluctant to pay. Majority of those who paid said that they did so due to the fear that if they did not do so they would lose benefits from other government welfare schemes. The 2nd re-treatment was therefore carried out free of charge nine months after the 1st re-treatment and thus achieved coverage of 70.4%. The study showed community acceptance to use ITNs as they perceived the benefit. Distribution and re-treatment of nets was thus possible through the PHC system, if done free of charge and when personnel from different departments, especially those at village level, were involved.

Population biology of Toxoplasma gondii: what's out and where did they come from

Until recently, Toxoplasma gondii was considered to be clonal with little genetic variability. In this paper we summarize recent genotyping data from chickens in Brazil, and pigs, lambs and white-tailed deer in the USA, to demonstrate the high genetic diversity and geographical distribution of T. gondii. A total of 149 T. gondii isolates from 13 geographical areas of Brazil and 182 T. gondii isolates from pigs, 53 isolates from sheep and 15 isolates from fetal white-tailed deer from USA were genotyped using the 10 RCFP-PCR genetic markers SAG1, SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1 and Apico. Genotyping of 149 T. gondii isolates from free range chickens in Brazil identified 58 genotype groups. No clonal type II lineage was found. Of the 253 isolates from animals from USA, 18 genotypes were identified, predominantly type II. These studies indicate a higher genetic diversity than previously recognized.

Treatment for congenital toxoplasmosis: finding out what works

Evidence for the effectiveness of prenatal or postnatal treatment for congenital toxoplasmosis will be critical to guide policy about prenatal and neonatal screening over the next 10 years, let alone the next 100. Randomised controlled trials are needed to address questions about treatment effectiveness, although cohort studies are also needed to provide information on prognosis, especially disability. Nowhere are such studies needed more than in South America where congenital toxoplasmosis is a major public health problem.

Toward Protein Biomarkers for Allergy: CD4+ T Cell Proteomics in Allergic and Nonallergic Subjects Sampled in and out of Pollen Season.

Allergy is an immunological disorder of the upper airways, lung, skin, and the gut with a growing prevalence over the last decades in Western countries. Atopy, the genetic predisposition for allergy, is strongly dependent on familial inheritance and environmental factors. These observations call for predictive markers of progression from atopy to allergy, a prerequisite to any active intervention in neonates and children (prophylactic interventions/primary prevention) or in adults (immunomodulatory interventions/secondary prevention). In an attempt to identify early biomarkers of the "atopic march" using minimally invasive sampling, CD4+ T cells from 20 adult volunteers (10 healthy and 10 with respiratory allergies) were isolated and quantitatively analyzed and their proteomes were compared in and out of pollen season (± antigen exposure). The proteome study based on high-resolution 2D gel electrophoresis revealed three candidate protein markers that distinguish the CD4+ T cell proteomes of normal from allergic individuals when sampled out of pollen season, namely Talin 1, Nipsnap homologue 3A, and Glutamate-cysteine ligase regulatory protein. Three proteins were found differentially expressed between the CD4+ T cell proteomes of normal and allergic subjects when sampled during pollen season: carbonyl reductase, glutathione S-transferase ω 1, and 2,4-dienoyl-CoA reductase. The results were partly validated by Western blotting.

Étude de la fonction de GLUT8 sur un modèle de souris "knock-out"

Résumé GLUT8 est la première des nouvelles isoformes des GLUT récemment identifiés. Il est fortement exprimé dans les testicules et plus faiblement dans les blastocystes, le cerveau, particulièrement au niveau de l'hippocampe, et le coeur. En conditions basales, il est retenu dans un compartiment intracellulaire. Si on l'exprime en surface cellulaire, par la mutation du motif d'internalisation dileucine, il transporte le glucose avec une bonne affinité. Dans le but d'étudier sa fonction au niveau de l'organisme, nous avons créé un modèle de knock out conditionnel, en entourant le dernier exon du gène de GLUT8 par deux sites loxP. En croisant nos souris avec une souche de souris transgénique exprimant la cre-recombinase dans les cellules de la lignée germinale, nous avons généré un modèle de souris portant la délétion totale de GLUT8 de manière constitutionnelle. Les statistiques effectuées sur les premières naissances indiquent qu'une partie des souris knock out ne survit pas, suggérant un rôle de GLUT8 au niveau du développement embryonnaire. Les souris qui ont survécu ne présentent toutefois pas d'anomalies durant la croissance et sont fertiles. Elles ont des taux de glucose et d'insuline sanguins normaux. Au niveau cérébral, la structure de l'hippocampe n'est pas modifiée par la suppression de GLUT8, cependant, les souris GLUT8-/- présentent une prolifération cellulaire augmentée dans le gyrus denté. Cette augmentation de division cellulaire pourrait être la réponse adaptée à une éventuelle augmentation de la mort cellulaire au niveau de l'hippocampe. Elles ne semblent toutefois pas présenter de défauts cognitifs majeurs dans le bassin de Morris en conditions normales. Toutefois, en conditions de jeûne, elles tendent à une meilleure mémorisation à court terme. Les études morphologiques et histologiques au niveau cardiaque n'ont pas révélé de d'hypertrophie au niveau ventriculaire. La stimulation de la contraction à l'isoprotérénol n'a pas mis en évidence de défaut d'adaptation des coeurs GLUT8-/-. Cependant l'analyse fonctionnelle par électrocardiogramme, en conditions basales, a montré une augmentation de la durée de l'onde P, suggérant un défaut dans la dépolarisation des oreillettes. Nos résultats indiquent que GLUT8 ne joue pas un rôle prédominant dans la survie et la fonction basale des souris. Il pourrait jouer un rôle plus important dans des situations stressantes pour l'organisme, comme l'hypoglycémie ou les conditions d'ischémie qui induiraient son expression à la membrane plasmique et stimuleraient le captage du glucose. Abstract GLUT8 was the first of the recently identified isoform of the GLUT family proteins. It is strongly expressed in the testis. It is also found at a lower level in the blastocyst, in heart and in the brain. Under basal conditions, it is retained in the intracellular compartment, but when the internalization motif dileucine is mutated, GLUT8 translocates to the plasma membrane and transports glucose with a relatively high affinity. To study its function in vivo, we created a conditional knock out mouse model. To do so, we targeted the last exon of the GLUT8 gene with two loxP sites. We then crossed these mice with a transgenic model expressing the cre-recombinase in the gem' line to generate a constitutional total knock out mouse. The statistics made on the first breedings showed that some of the knock out mice do not survive, suggesting a role of GLUT8 in the embryonic development. Conversely mice who survive do not show developmental defects and they are fertile with normal glucose and insulin blood levels. In the brain, the general structure of the hippocampus is not modified by the deletion of GLUT8. However, GLUT8-/- mice show an increase in the cell proliferation in the dentate gyms. This cell proliferation could be due to an increase in the cell death in the hippocampus. When tested in the morris water maze, these mice do not show any cognitive defects in the basal conditions, but they have a tendency to learn better in fasted conditions. The morphological and histological studies made at the heart level did not show any cardiac hypertrophy in the ventricles. The stimulation with isoproterenol did not show any adaptation defects in the GLUT8-/- hearts. However, the functional analysis made in basal conditions with the electrocardiogram showed an increase in the P wave length, suggesting a defect in the atrial depolarization in the knock out mice. Overall, our results show that GLUT8 does not play an important role in the basal general functions in the mice, but might play a more important role during whole organism stress. Hypoglycaemia or ischemia, for example could stimulate the GLUT8 translocation to the plasma membrane to increase specifically glucose uptake. Résumé tout public Les différentes cellules de l'organisme possèdent des propriétés particulières, qui leur permettent de maintenir les fonctions de l'organe auquel elles appartiennent. La membrane plasmique qui les délimite sélectionne les substances qui vont pénétrer à l'intérieur de la cellule et permet ainsi de maintenir un environnement interne constant. Le glucose est une source d'énergie importante pour la cellule et doit pouvoir pénétrer à l'intérieur de la cellule. Il utilise pour cela des protéines de transport qui le feront passer de part et d'autre de la membrane. Les protéines de la famille des GLUT (pour GLUcose Transporter) possèdent cette capacité. GLUT8 est un membre de la famille des GLUT identifié récemment. Il possède la capacité de transporter le glucose quand il se présente à la surface de la cellule. Il est principalement exprimé dans les testicules, dans le coeur et le cerveau et durant le développement embryonnaire. Son rôle n'est toutefois pas encore défini. Ce travail consiste à étudier la fonction de GLUT8 au niveau de l'organisme entier. Nous avons créé un modèle de souris dans lesquelles l'expression de GLUT8 a été supprimée pour mettre en évidence son importance dans le maintien de l'intégrité des fonctions du corps. Les observations effectuées sur les souris qui n'expriment plus GLUT8 nous indiquent que leurs cellules prolifèrent plus vite au niveau de l'hippocampe. L'hippocampe est une structure située dans le cerveau qui est impliquée dans les phénomènes d'apprentissage. Les souris qui ont été testées dans des tâches d'apprentissage n'ont malgré cela pas montré une amélioration de la mémorisation. Dans le coeur, la suppression de GLUT8 semble présenter un défaut quand on mesure l'activité électrique du coeur par électrocardiogramme. Toutefois, ils fonctionnent normalement et ne présentent pas de défauts morphologiques en conditions normales. Les expériences effectuées sur les modèles de souris indiquent que GLUT8 ne jouerait pas un rôle prédominant dans le fonctionnement normal du corps. Il pourrait exercer sa fonction dans des situations plus particulières comme l'hypoglycémie, où il permettrait une meilleure capacité à transporter le glucose dans les cellules.
